Transvaginal Ultrasound

Transvaginal Ultrasound

Sometimes a typical vaginal examination may be insufficient to detect anomalies for certain prevalent disorders that affect women. Transvaginal ultrasound can identify cancerous cells or benign tumors. Additionally, transvaginal ultrasound enhances diagnostic precision and facilitates earlier and more effective illness diagnosis and treatment. A tiny, high-frequency sound probe is placed into the vagina during transvaginal ultrasound to get a clear view of the pelvic organs. This covers the ovaries, fallopian tubes, uterus, and cervix. It is useful for identifying anomalies in the pelvic floor or for determining internal organ structures. Transvaginal ultrasound is also helpful for monitoring and confirming pregnancy.

Myoma Uteri

Myoma uteri is caused by abnormal alterations in the muscle cells of the uterus. It can develop in the uterine tissue, uterine cavity, or both. In addition, it can develop into a lump protruding from the uterus which may be felt by the patient. It is less common in women who experience menopause owing to hormone depletion and more common in those who reach reproductive age around the age of thirty.


  • Abnormal uterine bleeding: abnormal heavy or prolonged menstrual bleeding
  • Pelvic cramps: menstrual cramps or pelvic cramps without period
  • Frequent urination and constipation: compression of a large tumor on the bladder and rectum, causing frequent urination and constipation.
  • Infertility: enlargement of a tumor leads to compression on the uterus, preventing the implantation of the embryo


The cause of endometriosis is the growth of endometrial lining outside the uterus into a chocolate cyst or endometriosis cyst or adenomyosis, inducing inflammation and fibrosis in the affected area.


  • No obvious symptoms
  • Severe and prolonged menstrual cramps
  • Unusual tenesmus during menstruation
  • Abdominal pain during or following sexual intercourse
  • Infertility due to fibrosis of pelvic floor, making it unsuitable for fertilization

Ovarian Cyst
